A cross-sectional study investigated the association of hepatitis A seropositivity with environmental and personal risk factors among children in a United States-Mexico border community.
Hepatitis A serological markers and a questionnaire identifying risk factors were evaluated for 523 primary school children.
Of the children studied, 16.9% tested positive for total anti-hepatitis A virus.
Risk factors included being in the first grade, low maternal educational attainment, living in Mexico for more than 6 months, household crowding, and inadequate excreta disposal systems.
To decrease enteric disease, improvements in excreta disposal infrastructures and educational programs are needed.
Hepatitis A vaccine should be admin-istered before school age.
